Peer support is defined as support from a person who has experiential knowledge of a specific behavior or stressor and similar characteristics as the target population. Thus people with common illness experience can share knowledge and experience in a less hierarchical and reciprocal relationship compared to that between patients and health care professionals. A number of programs including health worker-led groups with peer exchange, peer-led face-to-face self management programs, peer coaches and remote peer support have reported encouraging results with short term improvement in metabolic or cognitive-psychological-behavioral dimensions, although these results are often limited by non-sustainability of changes and insufficient reach or adoption of programs by patients or health care workers. In the WHO report, health care experts from various disciplines concluded that whilst peer support is a promising approach for diabetes management, issues regarding methods of organization, types of programs and their integration with other clinical and outreach services remain to be addressed. Of note, there is a paucity of similar data in developing and low income areas which are hit hardest by this epidemic and where peer support program may offer great promise to make diabetes prevention and care program more sustainable and accessible, if implemented and evaluated systematically.
